These channels are applicable to UEK R2, DTrace for UEK R2, the beta release of
DTrace for UEK R2, and the beta release of UEK R3.

If your system is not already running the latest version of UEK R3 or UEK R4:

Use yum to update your system to use UEK R3 or UEK
R4.

# yum update

Reboot the system, selecting the Oracle Linux Server (3.8.13 for UEK R3 or
4.1.12 for UEK R4, as appropriate) kernel in the GRUB menu if it is not the default
kernel.

Use yum to install the DTrace utilities package:

# yum install dtrace-utils

If you subsequently use yum update to install a new kernel,
yum does not automatically install the matching
dtrace-modules package that the kernel requires. If the appropriate
dtrace-modules package for the running kernel is not present on the
system, the dtrace command downloads and installs the package from ULN. To
invoke this action without performing a trace, use a command such as the following:

# dtrace -l

Alternatively, run the following command to install the DTrace module that is appropriate
to the running kernel:

# yum install dtrace-modules-`uname -r`

If you want to implement a libdtrace consumer or develop a DTrace
provider, use yum to install the dtrace-utils-devel or
dtrace-modules-provider-headers package respectively.
